Simplified Fatigue Life Prediction

The calculation of fatigue lives has traditionally been a notoriously complex and difficult task. The prediction of fatigue life and failure locations for welded joints and welded structures, including spot welds, can often result in poor correlation with test data. The Verity Structural Stress Method was developed and patented by Battelle. It was a major breakthrough in the fatigue analysis of welded joints from finite element models.

Verity in fe-safe combines Verity for the fatigue of welded structures with the advanced features of fe-safe for fatigue analysis for finite element models. It allows companies to reduce or avoid the expense of testing to validate the integrity of designs and avoid the common practice of over-engineering due to the uncertainty of fatigue life.

Verity in fe-safe at a Glance

Removes the subjective decisions by the user, thereby increasing reliability and accuracy.
Works from nodal forces at the weld toe - not some subjective distance from the weld toe.
Uses a single master S-N curve for all welds and for all thicknesses of sheet and plate.
Offers consistent structural stress calculations regardless of mesh size or element types.
Achieves new levels of accuracy and reliability.
It is insensitive to mesh density.
Applicable to all types of welds, including spot welds, and all types of loading, including random vibration and sine sweep loading.
It is easy to use and automate.
Analyzes welded joints, spot welds and non-welded areas in a single run.
Validated by Battelle's Joint Industry Project using more than 3500 physical fatigue tests.
